WINDOW.

SPECIFICATION forming part of Letters Patent No. 684,574, dated October 22, 1901. Application filed April 19, 1901. Serial No. 56,618. (No model.)

T0 ctZZ whom it may concern:

Be it known that I, BENGT BENGTSSON, a subject of the King of Sweden and Norway, residing at St. James, in the county of Watonwan and State of Minnesota, have invented certain new and usefullmprovements in Win- (lows, of which the following is a specification.

My invention relates to windows, andhas for its object to provide a window that when the upper and lower sashes are closed they are held in a closed position at their tops and bottoms, respectively, and are made dust and weather proof by means of weather-stripping bearing directly against the sash and held in position by spring-pressure; that has means for releasing the fastenings at the top and bottom of the respective sashes and the weather-strips from engagement with the sashes, so they can be moved freely; means for returning the weather-strip to engagement with the sash, and thus hold the sash in any position when open, and means for fastening the sash when closed.

A further object of my invention is to provide means whereby any unskilled person may readily remove the windowsash for cleaning or painting or to provide a larger space for the passage of air during the summer months.

In the drawings, Figure l is a front view in elevation of my invention, partly broken away, the sash being closed. Fig. 2 is'a crosssection on the line a: at of Fig. 1, partly-broken away. Fig. 3 is a cross-section in elevation, showing the window partly open with the sash movably adjusted. Figs. 4: and 5 are detail views Fig. 6, a front elevation of the movable front of the frame; Fig. 7, a crosssection of Fig. 6 on line y y; Fig. 8, a front View of the lower sash; Figs. 9 and 10, details of the means of fastening the sash-cords to the sash.

In the drawings,-in which like letters of reference denote like parts throughout the several views, A represents the frame of a window, having the upper and lower sashes B and O. A portion of the front D of the frame, including the sill E, is loose from the frame A and is held in place by the bolts F and the cross-piece a on the frame A. The bolts F have springs f fastened to their ends,

which are held in the sockets F in the frame A' by the screws f.

F represents nut-s screwed on the bolt F, and f represents metal washers.

G is a bar mounted on the lower part of the frame A under the sill E, having a han dle G and lugs g, which are adapted to bear" W against the studs H on the bottom of the sill E.

On the side of the sill E toward the sash C are pins 6. On the lower part of the sash O are fixed metal plates 0, having holes 0' over sockets in said sash, adapted to receive the pins e.

The middle beads I are mounted loosely in grooves t in the frame A by means of the screws 1" and may be moved laterally.

K is the upper cross-bead, which is fastened to the heads I in any suitable manner,-the means shown being a stud on the end of the bead I, fitting in a socket in the bead K.

' L represents bolts fixed to the cross-bead K, having pins Z toward the sash B. The bolts L extend outwardly through the cross-piece a and have their ends turned up, forming an angular head L. M represents springs on said bolts L, bearing against a nut M and an angle-iron N on the frame A.

. 0 represents a rod mounted on the crosspiece Ct, formed with lugs 0, adapted to bear against the ends L of the bolts L and a crank 0 at one end.

P is a rod mounted on the stationary front of the frame A in any suitable manner, its] 1 upper end 19 being bent slightly and having a hole 19' in its end to receive the end of the crank 0 on the rod 0. 7

On the upper part of the sash B are fixed metal plates b, having holes I) over sockets in said sash which are adapted to receive the projections Z on the bolts L;

t On the inside of the lower part of the front D and the sill E toward the sash O, on the side of the beads I and K toward the sash -13, and on the edge of the upper cross-piece O of the sash 0, bearing against the lower crosspiece B of the sash B, is fitted rubber tubing Q, which acts as a weather-strip when the window is closed and operates to hold the sash in any position it maybe placed, as hereinafter described. i Y

On the top of each sash, near the sides, are

fixed metal plates R, which cover sockets S in the sash. The plates R are formed with a round hole r and a slot r. Each rope T has fastened at its end a metal button U, having a shank u, by means of the sleeve V. To'fasten the rope to the sash, the button U is inserted in the socket S through the hole '1' and the shank u pushed into the slot r. The rope T passes from the sash upward through holes IV over a pulley X to a weight Y, which is contained in a boXZ on the side of the frame A.

It will be readily seen that the tension of the springsfand M may be regulated by the nuts F and M, respectively.

The operation is as follows: The window being in the position shown in Fig. 1, to raise the lower sash turn the handle G upward, thus causing the lugs g on the rod G to bear against the studs Hand push the front D and sill E away from the sash C, causing the pins 6 to leave the holes in the plates 0. When the sash is at the height desired,release the handle G and the springsfwill then cause the front D to return to its normal position by pulling on the bolts F, and the weathenstrips Q 011 the sides of part D will hold the sash in any raised position. \Vhenever it is desired to raise or lower the lower sash, the same operation is repeated. When it is desired to lock the sash, the studs e enter the sockets c, and thus hold the sash securely and prevent it being raised. To operate the upper sash, push up on the rod P. This will cause the crank o to turn upward and the lugs 0 to bear against the angular heads L of the bolts L and draw the weather-strips on the beads I and K away from the sash B and the pinsZout of engagement with the holes I) in the metal plates Z). The upper sash can then be moved at will and held in any desired position by releasing the rod P,when the springs M will cause the beads I and K to resume their normal position and lock the sash by causing the weather-strips to bear against the sash B. The same operation is repeated whenever it is desired to move the sash.

To remove the sash from the frame, remove the nuts F from the bolts F. The part D can then be removed. Unfasten the sash-cords from the lower sash O and take out the sash. Remove the beads I by unscrewing the screws 1 lower the upper sash B, unfasten the sashcords, and the sash can be removed. The buttons Uprevent the end of the sash-cords going any farther than the holes W.
